Flop: Since he's so loose pf I guess there could be a lot of worse Ax hands in his range. I'm not sure how many of these he would raise on the flop though? Also possible 99/55 raising for value and protection. Or a bluff that doesn't believe I have the A I guess.

Is calling to reevaluate on the turn ok? And should I be planning on bet/folding the turn if its a blank?

Turn: Since he bet so big I'm not really sure what he could have. If I had a stronger Ax I would maybe continue or? I didn't really see what he could be betting like that, seemed strong though.

While there ain't many worse Ax hands and you mainly beat only a flushdraw. Therefore I'd rather prefer just Bet/Folding the flop while we even don't know the opponent that much. A9/A5/55/99 already beat us and of course all the AJ/AQ/AK type of hands as well while he may easily even have them in his range.
